摘　　要：介绍了反硝化除磷的基本原理,对其影响因素诸如污泥龄、NO2-和NO3-的浓度、溶解氧、好氧池与缺氧池体积比及内碳源等进行讨论和分析,为反硝化除磷过程的模拟、试验研究和实际的应用提供了参考和依据。The denitrifying phosphorous removal process, the simultaneous removal of nitrogen and phosphorous that can be achieved by using the same substrate, is a method with practical prospect for municipal sewage treatment. The principle of the denitrifying phosphorous removal process is introduced, the influencing factors such as SRT, mass concentration of NO2-and NO3^-, hydraulic retention time, dissolved oxygen, volumetric ratio of aerobic and anoxic reactors, PH value and PHB and so on are discussed and provide the basis for modeling, experimental study and practical application of the denitrifying phosphorous removal process.
